To all whom it may concern: 7

Be it known that l, Jonn T. ALLMAND,

a citizen of the UnitedStates, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in 'VVeather-Strips, and declare the following to be a full, clear, and exact description of the enable others'skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part ofthi's specification.

This invention relates to weather strips for Windshields having overlapping panels. lt is now customary to build Windshields having panels the meeting edges of which have no sashes, and in both rainy and cold weather the necessary opening left between the edges of the windshield panels makes an objectionable place for drafts and water tov come through. Removable weather strips for panels having edges which do not overlap have been designed but these are unadapted for use in connection with panels having overlapping edges.

I have designed a strip which not only serves to fill up the opening between the overlapping panels but also serves as a check to prevent the two panels clashing together when carelessly handled or by the ars due to a rough road. The checking is effected by a yieldable flange so that there is no liability of breaking the panels due to vibration of the if the contacting more or less solid.

Another important feature of this strip part of the strip were is that it is so designed that it is of mini-- mum vertical width and consequently pre seats a minimum line of obstruction to the vision.

In the drawings,- I

Figure 1 is a sectional perspective of a provided with my newweather windshield strip.

Fig. 2 is a section in detail showing how the sealing flange of the strip is made to press tightly against the overlapping panel.-

lreferably the strip is made out of rubher and in a rough way it has a cross section like the letter W. Preferably the strip is carried by the top ec ge of the inner panel and hence the W is inverted. In

same, such as will bration, the

same which might result Patented May is, iaia. seriainaioaaoa i another sense, the strip is a double channel strip with one channel beside the other, and one a constricting channel and the other an expanding channel; that is to say, the tendency of the wallsof one channel is inward while the tendency of the walls of the other channel is outward. These tendencies have a material functional that is, the-walls of one channel 0; fit over the edge of-one panel and cause the strip to cling to this panel as shown on the lower panel of Fig. 2. However, the strip may be easily pulled oil when the nature of the weather does not require further-use The other channel I) tending to expand, forms the sealing flange c adapted to press with some force against the inside of the outside channel, thereby insuring a water and almost air-tight inclosure.

When the panels are clashed together, as they often are I through carelessness, or

value, and

when the panels tend to clash through vi- I sealing strip 0 acts as a checking device to yiel dingly avoid clashing.

It is also to be noted that by the arrangement of the sealing strip 0 and the two other strips that form the channels all side by side, the obstruction to the vision is only about one-half of'what it is with the strips of the prior art designed for use with the non-lapping panels.

This strip being made'of rubber may be easily taken off and may be rolled up in a spiral and inserted in a pocket in the car or any other convenient place.

What I claim is:

g g 1. A weather strip for lapped windshield panels constructed of rubber or distortable material and havmg a W cross sectlon iorming a channel adapted to fit over the edge of one panel, and a sealingfiange to engage the other panel of Windshields havlng lapping panel ed es.

2. A weather strip for lapped windshield panels,

of roughly inverted the Walls of one channel tend together and of the expansible channel serving as a sealing strip thrusting against the other Wind; shield panel.

The combination with a Windshield havin panels Whose meeting edges lap, of a rubber or other distortable material strip W shape in which panel for the purpose of ex- L. The combination with a Windshield having meeting edges that overlap, of a strip constructed ofrubber or other distortable material, comprising three Walls forming two channels, one channel being adapted to be expanded to fit the walls over the edge of one panel'so the strip will cling thereto and the walls of the other channel being constricted by engagement of the other panel thereagainst so as to securely hold'the outer .wall againstthe panel in weather-tight relation. v

In testimony whereof, I sign-this specification.
